| 327 | help |
| 328 | On DiskOnChip devices shipped with the INFTL filesystem (Millennium |
| 329 | and 2000 TSOP/Alon), Linux reserves some space at the end of the |
| 330 | device for the Bad Block Table (BBT). If you have existing INFTL |
| 331 | data on your device (created by non-Linux tools such as M-Systems' |
| 332 | DOS drivers), your data might overlap the area Linux wants to use for |
| 333 | the BBT. If this is a concern for you, leave this option disabled and |
| 334 | Linux will not write BBT data into this area. |
| 335 | The downside of leaving this option disabled is that if bad blocks |
| 336 | are detected by Linux, they will not be recorded in the BBT, which |
| 337 | could cause future problems. |
| 338 | Once you enable this option, new filesystems (INFTL or others, created |
| 339 | in Linux or other operating systems) will not use the reserved area. |
| 340 | The only reason not to enable this option is to prevent damage to |
| 341 | preexisting filesystems. |
| 342 | Even if you leave this disabled, you can enable BBT writes at module |
| 343 | load time (assuming you build diskonchip as a module) with the module |
| 344 | parameter "inftl_bbt_write=1". |
